Why are you afraid of answering the question?
You haven't asked an answerable question. The question, as you asked it, contains innumerable hidden assumptions about the nature of time and existence.
The simple answer, according to physicists is that the observable universe has a point in its history beyond which the ordinary definition of time loses its meaning.
But physics also knows that it doesn't know everything and hasn't observed everything. There are observable effects on galaxies that imply we haven't observed or meaningfully described more than a fraction of what we call matter and energy.
So even at the level of observable, physical reality, your question is unanswerable.
